Crime Incidents in 2016

On February 1 2020, the methodology of geography assignments of crime data was modified to increase accuracy. From January 1 2020 going forward, all crime data will have Ward, ANC, SMD, BID, Neighborhood Cluster, Voting Precinct, Block Group and Census Tract values calculated prior to, rather than after, anonymization to the block level. This change impacts approximately one percent of Ward assignments. This change was not applied to datasets pre-2020.

2020年2月1日，针对犯罪数据的地理分配方法完成修订，以提升数据准确性。自2020年1月1日起，所有犯罪数据的选区（Ward）、邻里咨询委员会（ANC）、单一成员区（SMD）、商业改善区（BID）、社区集群（Neighborhood Cluster）、投票分区（Voting Precinct）、街区组（Block Group）及普查区（Census Tract）字段值，将在进行街区级匿名化处理前完成计算，而非匿名化处理后。此次修订约影响1%的选区分配结果。该修订未适用于2020年之前的数据集。
